About the role
This interview examines how you lead credit risk modelling from data selection to live portfolio monitoring. The panel wants statistical depth, lending judgement and a clear approach to explainability, fairness and governance.
How to prepare
- Review selection bias, reject inference, calibration and validation for lending models.
- Practise connecting model measures to approval quality, losses and customer impact.
- Prepare a case where you detected drift or challenged a misleading model result.
- Think through fairness and explainability when alternative data improves prediction.
- Be ready to describe how scientists, credit risk and product owners approve model changes.
Common mistakes
- Choosing a model from one statistical measure without considering calibration or portfolio outcomes.
- Ignoring the selection bias created by historical approval rules.
- Treating explainability and fairness as checks to add after deployment.
- Discussing model performance without a monitoring and intervention plan.
